(CNN) - U.S. Secretary of State Hillary Clinton traveled to the epicenter of Africa's longest war Tuesday to try to help victims, especially those of sexual violence, of a regional conflict that's dragged on more than a decade.
She delivered a blunt message to Prime Minister Adolphe Muzito of the Democratic Republic of Congo on Monday when he hosted a dinner in her honor.
"There must be an end to widespread financial corruption and abuses of human rights and women's rights," she said. "There must be an improvement in governance and the respect for the rule of law."
She also called for "changes in the business climate, changes in the rules and regulations that involve contracts and the protection of property" in order to promote foreign investment.
On Tuesday, she offered help to the country's president, Joseph Kabila.
"I offered and the president accepted my sending of legal and financial and other technical experts to the DRC to provide specific suggestions about how to overcome these very serious obstacles to the potential of this country," she said, according to a pool report from Goma, in the east of the country.
Clinton took a small U.N. plane on the 1,000-mile trip from Kinshasa to Goma, the scene of intense fighting over the past several years.
The smaller aircraft was necessary because the U.S. plane being used on her seven-nation Africa trip is too big for the local landing strip, Clinton told reporters Monday.
The secretary is due to visit U.N. peacekeepers in Goma, and is also expected to take part in a roundtable discussion with victims of sexual and gender-based violence in the country.
The Congo conflict has involved several countries and resulted in an estimated 5 million deaths from fighting and collateral problems such as disease and starvation, according to an International Rescue Committee survey conducted more than a year ago. In addition, tens of thousands of women have been raped in the ongoing regional strife stoked by competition for mineral riches.
"I will be pressing very hard for not just assistance to help those who are being abused and mistreated, in particular the women who are turned into weapons of war through the rape they experience, but also looking for ways to try to end this conflict," Clinton said.
She opened her Africa trip in Nairobi, Kenya, then went to South Africa and Angola. After Congo, she will travel to Nigeria, Liberia and Cape Verde.
The Obama administration is using Clinton's tour to promote development and good governance and underscore the president's commitment to Africa.
